Regular magic infusions are the best way for a human to become a witch! Probably.

I don't see any other galleries with dolcett?

There is a slightly older gallery posted by someone else who is not the artist. In that one there was Dolcett, but the artist pointed out that Lilith, (the victim) would still be alive and fine as we have seen witches get dismembered in the show and still be just fine.

Plus, that one in particular is unrelated to the theme of the series (being Luz getting dicked down by futa witches) and kind of just draws all the attention to itself instead of the gallery as a whole.
